Yes, I left out that my regular alloy is BHN 16, all bullets are gas checked. I did try some straight Linotype (BHN 21) bullets some time ago, leading was reduced, but still present, it would probably just be more shots fired between scrubbing.

I have also tried different size bullets, If I go to a .431 sizing die the leading increases, .430 seems to be about right for size.

The lead appears to be slowly filling tiny machine marks left in the grooves, I have not seen any lead on the lands anywhere, and they are visibly smoother and shinier.

At this poing I'm leaning towards hand lapping, I can't seeem to find a consensus if fire lapping a revolver is good or bad.
